Here are the steps to take.
1. Establish whether or not you have
a connection between your camera/computer by going to your start
button, control panel, system, hardware tab and device manager. The
camera must be powered on and in playback mode (should automatically go
to playback mode when connected, camera's screen should go black if
there is a connection). Make sure you have a fully or nearly fully
charged battery in your camera.
2. Once in device manager, look
under Imaging Devices. If your camera is properly connected it should
show up as Canon Powershot SD800. If it shows a yellow exclamation
point, there is a driver issue, and even if it doesn't show a yellow
exclamation point, you may want to update your driver anyway by right
clicking and having the system search automatically for driver updates.
If download of driver begins, great...once finished, restart camera and
your problem may be resolved.
3. If there are any other imaging devices, you may have to temporarily disable them to avoid conflicts.
If you have any other imaging software running, exit or close the
program in your system tray (down by your clock in the right hand
corner of your computer's desktop.
5. Try again to connect.
6. If you are on a desktop, try a rear usb
port vs. a front port. You can also try a different port on a laptop.
After each change, try restarting camera to establish connection.
Go to start/My Computer and look for the icon for your camera...you
will be able to download images even without Canon software loaded onto
computer so this is not a software issue if you have no hardware
connection. If you see the icon, right click on it and choose Get or
Import pictures. From there the default Microsoft scanner and camera wizard should launch and you will be able to import your images.
If still no connection, try going to Start/Run and type in services.msc
here you are looking for 4 services to be running. Check under status
of each service and make sure it reads that each of these services are
- Canon Camera Access Library 8 (if Canon software loaded)
- SSDP discovery service
- Universal Plug and Play Device Host
- Windows Image Acquisition
Once all of these
services are started on your computer, restart camera once again. If
any of the last three services are not on your computer or are not
started, connecting will be a problem.
If all of these steps
fail, try purchasing an SD card reader from your local electronics
store for around $12 and download images from there. Canon also offers
lifetime technical support for your Powershot, so give them a call if none of these steps work or if you would like someone to walk you through it.
Best of luck to you!
